Using a sophisticated 9 degrees-of-freedom sensor, Shaknspin can accurately measure the rotational speed of your turntable platter, 500 times per second.

The Speed option allows the platter speed to be continuously displayed allowing you to confirm that all is well.


Wow&Flutter analysis is another method of operation. Following a brief measuring period, the following indicators are calculated and displayed:

  • Average speed in RPM
  • Average speed deviation
  • Max / min speed variation 
  • Max% / min% speed variation 
  • High pass filtered max / min speed variation
  • W&F DIN
  • W&F WRMS
  • W&F peak-to-peak
  • W&F peak-to-peak 2sigma
  • Wow
  • Flutter
  • W&F (DIN weighted)
  • Modulation frequency (primary)
  • Modulation frequency (secondary)
  • Jitter (average speed change / second)

More information about these indicators can be found here, and the complete User Manual can be downloaded here.

This is very valuable information,  allowing you to see the characteristics of the platter rotation in terms of speed stability and giving clues to where any issues might be.

Graphical representations of the speed variation, flutter component and calculated average are also available.

But there’s more… A spectrogram of the modulating frequencies and an histogram for the speed variation are also immediately available.


At the end of each measuring session, you can optionally choose to download the collected data into your smartphone, for additional analysis and / or archiving.

The built-in Bluetooth connection allows this quick and easy transfer of data.

The common CSV file format generated by our Android app, allows the data to be easily read into Excel and analyzed or graphed with the supplied template.


After generating the CSV file, you can submit it to our growing database of turntable performance characteristics. Just email it to us at and we will add it ourselves.

At anytime, you can check the current database by downloading the spreadsheet here.
